The arrested North Korean agent, Kim Hyon-Hui, was born on December 22, 1961 in the Japanese calendar. But her birthday was the 100th anniversary of the First Japanese Embassy to Europe (December 22, 1861 in the Japanese calendar).

On July 20, 2010, she visited Japan. But the Japanese authorities waived strict immigration controls to allow her to meet the relatives of two Japanese citizens snatched by North Korean agents in the late 1970s. Naturally, critics denounced the visit as a stunt designed to deflect attention from Japan's failure to establish the fates of Megumi Yokota and other abductees. Hyon-Hui had already spoken to some of the victims' families and was not expected to offer any new information.
